Title: Improvements in or relating to the manufacture of plain bearings
IPC: B22F7/04
Filed: 1949-03-01
Abstract: In a bearing comprising a sintered copper lead alloy, the composition is graded from a relatively high lead content at the bearing surface to a reduced lead content further from the bearing surface.  The sintered material may be bonded to a relatively strong backing such as steel.  A method of making the bearing comprises electro-plating a steel backing with copper, applying on to the copper-plated surface a bonding layer of mixed metal powders containing a high percentage of tin, thereafter applying a multiplicity of graded copper lead compositions in which the ratio of lead to copper increases from layer to layer and reaches a maximum at the bearing surface, and then sintering the composite layer in a reducing atmosphere.  After sintering, the bearing is compacted by pressing.  The successive layers containing an increasing ratio of lead may also contain a decreasing ratio of tin.  Specifications 662,955, [Group XXXII], and 676,209,  Reference has been directed by the Comptroller to Specification 496,763.

Abstract: 1284851 Hooks M TANIGUCHI 5 March 1971 6168/71 Heading E2A A hook for releasably engaging a load carrying element 15 supporting a load to be lowered to a load bearing surface by a lifting and lowering device O, comprises a hook part I for releasably engaging said element; connecting means 12 engaging an elongate guide 11 provided by said hook part for pivotally connecting said hook part to said device for support thereby, and allowing swinging movement of said hook part between limit positions when an abutment 4 provided by said hook part engages a surface during lowering; and means 6 for restricting relative pivotal movement between said hook part and said connecting means one with respect to the other; the arrangement being such that in use, when the load is lowered to the load bearing surface by the device, further lowering of said hook by the device reduces tension between the element and said hook part when the abutment contacts the surface whereby said hook part swings towards one of said limit positions so as to permit disengagement of the element and said hook part one with respect to the other, and lifting of the device permits said hook part to pivot to said one limit position to clear the element. As shown the guide 11 is a long curved slot and the connecting means consists of a shackle to which the device O can be attached and a pin 13 which passes through apertures in the limbs of the shackle and through the slot 11, the shackle carrying two mousing pieces which when the hook part is in one position closes the mouth of the hook part, a shackle 7 being attached to the hook part adjacent one end and a float 21 being attached by means of a link to an aperture 5 near the opposite end of the hook part the float being attached near the abutment 4 of the hook part; for raising a load the hook part is disposed in the position shown in Fig. 1 in which the load carrying element is a sling 15; when the load is lowered and becomes supported the abutment 14 causes the hook part to pivot anticlockwise so that the sling becomes detached from the hook part and subsequently raising the hook causes the pin 13 to move to the other end of the slot 11 so reversing the position of the hook part; the shackle 7 is attached to a tie line 20 to assist in pivoting the hook part to the releasing position. The float 21 acts to pivot the hook part to the releasing position if the load is lowered into water and so detaches the hook part from the load. The means 6 is the pin by which the shackle 7 is attached to the hook part and it abuts the shackle of the connecting means to restrict the pivoted movement of the hook part in the clockwise direction.

Title: Method of making paperboard boxes
IPC: B31B50/58
Filed: 1957-02-25
Abstract: 813,417. Making cartons. BOMBARD, L. E. LA. Feb. 25, 1957, No. 6207/57. Class 18. In forming a carton by creasing a blank and folding it on two creases to produce a flattened tube consisting of side walls and end closure panels, the separating of the end closure panels at the fold lines to form closure flaps is performed by cutting along these fold lines after the blank is folded. The method is particularly applicable to cartons of double face corrugated material. Blanks 73 are carried by a conveyer 70 beneath creasing rolls 76, 77 which may also form centre cuts 45, 46. Belts 80 fold the blank to tubular form, the blanks then being allowed to pile up on a conveyer 72 to give time for drying of the glue lap adhesive. A conveyer 71 passes the blanks between cutters 81 and 82 which separate the closure panels by cuts 50-53. The cuts 45, 46 may be omitted in the initial stage and the tube, after cutting at 50-53, may be refolded on the remaining longitudinal creases. The glue lap may extend the full length of the tube and cuts such as 50-53 then separate the remaining joined closure panels along the glue lap and along the fold opposed to it. The cuts are curved at their inner ends to improve the sift proof qualities of the carton.
